The Fermi-Löwdin Orbital Self-Interaction Correction

The FLOSIC Center is one of several Computational Chemical Sciences Centers funded by the U.S. Department of Energy in September 2017. Central Michigan University (CMU) is the lead institution in FLO-SIC, joined by research teams from Temple University, the University of Texas-El Paso, the University of Florida, and the University of Pittsburgh. The Center’s research is aimed at developing improved first-principles methods for computationally modeling molecules and materials at the atomic level. The ultimate goal of the Center is to produce open source software that allows efficient and predictive modeling of materials without unphysical effects of electron self-interaction, the major flaw present in existing methods.

  • FLO-SIC IN THE NEWS Two media stories about research done at the University of Pittsburgh recently appeared online.  See one story here and the other here.
  • WORKSHOP on Self-Interaction  FLO-SIC Center lead PI Koblar Jackson co-organized an international workshop entitled "Quo Vadis Self-interaction correction" with Prof. Jens Kortus of the TU-Bergakademie Freiberg.  The workshop was held in Freiberg, Germany and featured speakers from Europe, the U.K., Israel, and the United States.  Three FLO-SIC Center PI's, John Perdew, Juan Peralta, and Rajendra Zope, gave invited talks.  See the workshop website here.
